The diamond quality assessment criteria
All diamonds are evaluated based on 4 criteria, the 4 Cs: Carat (the weight), Color (how white a diamond is), Clarity (the amount of inclusions in the diamond) and the Cut (the quality of the cut itself).
Courbet selects each of its laboratory created diamonds to offer only the whitest color superior or equal to F, the purest diamonds superior or equal to VS with the best cuts.
To these 4Cs, Courbet adds a fifth one: the C of conscience. By using laboratory grown diamonds, Courbet embrases an innovative, clean and socially respectful alternative. Find out more.
